MATLAB: Converting a complex number to polar form and finding it’s magnitude

Question

z = (((-(3)^(0.5) + 3i).^4) * exp((-5i*pi/6))^3)/(2 + 2i)^2; how to convert this into it's polar form and find it's magnitude?

Answer 1

r = abs(z);
theta = atan2(imag(z),real(z));

Also...

r = abs(z);
theta = angle(z);
